Sorry, I not understand where you see error.
In OrdaSoft membership website software
If you not wish check manual every user, this only 1 way check email of person who wish register on your site. So if user added corrected email at registration time - he will receive to that email "activation link" whist help this link - user will continue registration. If email invalid user not receive activation link..
But in every "Simple membership user group" you may change how you will check/approve every new user. Or you will need change this in Joomla Users settings - If you not use OrdaSoft membership website software
